'03 XLT A/C Noise

[redchevelle72]

I have an '03 Explorer XLT that is making a tapping noise when the A/C is on. No tapping when A/C is off. It has not made this noise before. The A/C works great. The tapping is coming from the A/C compressor. If anyone has any idea if this is normal or may be an indication of a problem please give me your opinion.

Thanks
